IMPROVEMENT IN FLIERS FOR SPINNING.

I will endeavor to explain the nature of my invention.

Pressers for spinning-iiiers heretofore used are adapted to headlessbobbins, so called, and cannot be applied to the sort of bobbins calledhead-bobbins, and represented in Fig. 2. They cannot be so appliedfortwo reasonsviz., first, the form of the pressers deliveryarm, and,second, the immobility of the presser-arm in more than one direction;and Iclaim to have overcome both of these objections by an improvementthat will give to the millions of head-bobbins in use a treble value,inasmuch as by it not only three times the amount of roving can be woundupon such a bobbin, thus made equal to any other, wound with a presser,in solidity and compactness. p

It is difficult to explain how pressers now in use fail toV fill theentire barrel ofthe bobbinwithout drawings to illustrate, though I willrefer to Letters Patent issued to myself December 3, 186i, for thecommon form of the delivery-arm. Such pressers will not permit theroving to run close to either head of the bobbin, but leave a space atthe end of the band next to the head unwound and uncovered, into whichthe roving, as it increases upon the bobbin, falls and binds, therebycausing frequent breakagein both winding and unwinding the roving. Sogreat in practice is this objection that it is believed that nopresspart of Letters Patent No. 36,864, dat

and I do hereby declare that full and exact description ed November 4,186:2.

ers now in use are employed upon head-bobbins.

To enable others skilled in the art to make and use my invention,I willproceed to describe its construction and operation. l

In the first place I forge apiece of iron, ld., Figs. 2, 3, 4, 5, withan elbow in same, and solder d to h, the iiier-tube at a proper distancebelow j, Figs. 2, 3, 4, 5, this distance being very nearlythe length ofd, so as to bring arm b, when in use, opposite or equal in height to thelower part of the delivery-notchj in h., Figs. 2,4. To d, near its junction with h,I solder the spiral spring a, made of steelandmspringtempered. a is then coiled around d to a point above d as faras necessary, for the purpose hereinafter described. Then ais extendedat right angles with its coil, forming b,or arm of the presser,until itreaches the desired length of an arm, when a is crooked at c into theform of a hook, as shown in Figs. 2, 4.. Thus a the spring, b-the arm,and c the delivery, of the presser, are formed of one and the same pieceof steel wire. The object of making these parts of one piece is to givearm sufficient elasticity to adapt itself to the head of the bobbin. Asthe bobbin, Fig. 2, in process of being wound goes upward with itsspindle toward the dotted red lines above, the roving t winds in thedirection indicated by the red line t p, Fig fully raised,and the head soccupies the space (indicated by dotted red 1ines,) the inner side of Sstrikes against b and bends or swings it upward, t in the meantimefalling down toward o, Fig. 2. Then as the bobbin changes its directionto pass down this reversed motion throws t below the middle of the hookc, and as the bobbin falls t, by the bobbins new direction and thethread already wound,takes the place o t, Fig. 2, and thus t closesaround f at its junction with s as completely and evenly as upon anyother portion of f, the barrel of the bobbin. This throwing t close to sis greatly aided by the smooth hook at c, over the end of which treadily moves.

In pressers for fliers now in use it will be observed that their'arms bof the pressers are made to vibrate or move only in onedirectionl-viz.,ahorizontal direction-corresponding to the line n m,Fig. 6,and their construction is such as to preclude motion of b in anythe presser- 2. When the bobbin is other direction. N ow, I give to thepresserarm c an additional and new motion in the direction of dottedlines k Z, Fig., 2V-a perpendicular motion of b. By giving b this newmotion at right angles with its common one on the line n m, Fig. 6, I amable to give to b at its end at c a sort of circular motion (see Fig. 4)that c describes as it plays over the bobbin at the time of the bobbinsshifting its perpendicular directi0n,and this resultant m0- tion ispeculiarly adapted to throwing the roving closeto the head of .a'bobbin, assisted as it is by thehook c.

To adapt myimprovement to the variations of the running of a bobbin, andalso to the different lengths of head-bobbins, which vary frequentlyabout one-fourth of an inch,'I cxtend the coil of a a short space aboved, where el is shown by dotted lines, Figs. 2, 3, 5, so that thepresser-,arm Z1, in addition to its own elasticity, may have the benefitof a slight lateral or side motion of' the top of coil a, thus gi vingto c a greater perpendicular sweep than would be possible if d ran closeup to the angle where coil a branches off at right angles to form b,andgiving also tob sufcient play to meet the variations of the running ofthe same bobbin from time to time.

a is coiled and fashioned as above described before being soldered ontoLas described; but I contemplate using a on (Las described,with outsoldering a and d to cach other, in this way,viz: At the lower end ofa,I attach a stop that strikes against h and prevents a from turningaround d, which contrivance is very serviceable in repairing a, b, or c,as all of these parts,made of one piece, can be taken ofi" of d bylifting them up and off of d.

What I cla-im, and desire to secure by Letters Patent, is`

1. The construction of a presser for headbobbins,by combining the spiralspring a, the arm b, and the hook c of one and the same piece of steelwire, formed and arranged substantially as described, for the purposesherein set forth.k

2. The combination ofthe arm, spring,and hook, whether in one or morepieces, when so arranged as to give the hook or delivering-iinger thevertical play necessary to lay the yarn close to the upper and lowerheads of the bobbin, as set forth.
